From 777a45b458660b18d7d7c3e0d874d08650c99cd2 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Fri, 3 Nov 2017 13:20:54 -0400 Subject: [PATCH] arch/tile: Implement ->set_state_oneshot_stopped() set_state_oneshot_stopped() is called by the clkevt core, when the next event is required at an expiry time of 'KTIME_MAX'. This normally happens with NO_HZ_{IDLE|FULL} in both LOWRES/HIGHRES modes. This patch makes the clockevent device to stop on such an event, to avoid spurious interrupts, as explained by: commit 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state").
